New Idea for a Semi-auto Beltfed Rifle

After seeing some M249 bolt assemblies, I noticed how close in size the bolt lugs are to an AK.

I think it is possible to use a M249 bolt assembly and feed assembly combined with various AK parts to make a "shadow" PKM beltfed rifle in 5.56MM caliber. Perhaps even in 5.45MM caliber. Keeping in mind that the PKM is pretty much an unside down AK.

Of course, you will have to use a blank AK receiver because the guide rails will have to be closer together.
